PROPELLING MECHANISM FOR CASH OR BUNDLE CARRIERS.

SPECIFICATION forming part of Letters Patent No. 600,628, dated March 15, 1898. Application filed October 9, 1897. Serial No. 654,714. (No model.)

Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in PropellingMechanism for Cash or Bundle Carriers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a cheap, neat, and durable mechanism for delivering a propelling impulse to a cash or bundle carrier. It has been common heretofore to furnish such impulse by means of stretched elastic cord, but these cords deteriorate and lose their elasticity and require frequent renewals. My invention overcomes this difficulty by using a helical spring so arranged and supported as to be Very eflicient in service and neat in appearance.

The invention may best be said to consist in the combination of parts hereinafter described, and definitely pointed out in the claims.

The drawings show my invention embodied in the best form at present known to me.

Figure 1 is a side elevation of such embodi-' ment; Fig. 2, a plan thereof; Fig. 3, a horizontal section on line 3 3 of Fig. 1; and Fig. 4., a vertical section on the line 4. at of that figure, looking in the direction of the arrow.

Referring to the parts by letter, A represents a substantially vertical standard depending from the ceiling or otherwise supported and carrying at its lower end a peculiarly-shaped casting or head a. The standard is braced by the guy-rod a, extending from the head a, or by other or additional guys. The head a is preferably hollow throughout and has an elbow a at its lower end. From this elbow there projects in the direction in which the car is to travel a rod B, preferably square in cross-section. The

wire 0, forming the path for the car, extends through a longitudinal hole in the rod B and terminates in the eye D, which is within the elbow of the head a, and the shank of which extends through that head and carries a nut cl, by which the tension on the wire may be adjusted.

Surrounding the rod Bis a helical spring E,

secured at its rear end to the block F and at its, forward end to the block G, the former block being slidable upon the rod B and being preferably rectangular in cross-section and the latter block slidable upon the wire 0 and being preferably round.

H represents the car for cash or bundles, which is suitably supported by wheels on the wire 0 and is adapted to be acted upon in its terminal position by the helical spring. The forward block G bears against the car in this position through the intervention of the rubberbuffer-block O. A similar buffer-block O on the rear side of the block G relieves shock when that block bears against the forward end of the rod B, while a third buffer, in the form of a rubber washer P, surrounding the rod B, forms a cushion between the block F and the elbow a The rod B, being square in section, prevents turning of the block F as it slides and forms a sufficient support and guide for the helical spring without occasioningundue friction.

r The head a extends forward above the rod B preferably in the form of a tube a having a web a on its upper side. To the forward end of this web is pivoted a latch J, the pivotingbeing accomplished through the intervention of the plate K, which is hinged by a pivot-bolt j to the rear end of said latch and is bolted to said web (prefefably adjustably) bya bolt is. This latch J consists of the plate j, having the U-shaped bailj extending forward and downward therefrom, as shown. The forward end of this bail is adapted to take over a hook or projection h on the car H and thereby retain the latter. Aset-screw j extending through the plate j and bearing against the forward end of the web or, limits the downward movement of the latch J.

Pivoted to the web a, preferably a little back of and below the pivot of the latch J, is the operating-lever L. This lever, which is preferably an integral casting, is composed of two side bars Z, standing on each side of the tube a and the spring E and uniting at Z and there merging into a shank for the handle Z and also uniting in front of the pivot of the lever and forming the two arms Z and Z The lever is preferably curved, as shown,

and. through the two side bars thereof are formed the curved slots Z A pin f projects laterally in each direction from the block F into these slots, whereby when the lever is moved forward the block F moveswith it and the spring E is compressed behind the car.

A helical spring M stands within the tube a and has its forward end secured to the arm Z of the lever L and its rear end to the cast ing a by means of the shanked eye m or in other .suitable manner. This spring thus exerts its tendency to draw the lever L into its rear position.

Extending upward from the arm Z of the lever is the bar N, which has its upper end bent to form a lip n, which projects over the plate j of the latch J Vhen the lever L is approaching its extreme forward position,the forward end of the arm Z impinges against the under side of the plate j, as shown in dotted lines in Fig. 1, and lifts that latch, releasing the'oar, and the lip it limits the upward movement of the latch under the impulse thus given it.

The parts at rest being as shown in Fig. 1, the operation of the propelling mechanism is as follows: The lever L is forced forward by the hand of the operator,who grasps the handle Z This movement of the lever drives the block F forward and compresses the spring E between that block and the car, the rod B preventing any distortion of the spring. When the lever L has been drawn into the position shown in the dotted lines in Fig. 1, the spring is sufficiently compressed to force the car the required distance and the forward end Z of the lever impinges against the under side of the latch J, and thus the continued movement of the lever withdraws the latch and frees the car,which the spring E, elongating,

- mechanism, together-with the various rubber cushions referred to, while the operating-lever L is returned to its initial position by the spring M, the mechanism being thus brought into position to receive the car as it returns.

Having thus described my invention, I claim 1. In a mechanism for propelling a cash or bundle carrier, in combination, a standard, a stationary rod extending therefrom, a helical spring surrounding said rod, a track for the carrier extending from the forward end of said rod, means for compressing the spring while around said rod so as to bear againsta carrier on the track, and means for releasing such carrier when the spring is compressed the desired amount, substantially as described.
